Last year, after years of not playing with 22s, I bought a couple of rifles for my sons and I to play with. I also purchased 2 P22s. Like I said it had been decades since I bought 22 ammo and knew nothing about it. I went to Sports Authority and bought a brick and it rang up @ $1.69. Well needless to say I grabbed a shopping cart and bought all they had. 38 bricks. It was Winchester High Velocity Super X Hollow Point and it does have a jacket.
If it's still made I want to let it be known that it cycles in the P22s flawlessly. I never gave the ammo a thought till this thread. I am down to about 12 bricks and think I will use this ammo for the P22s and buy other ammo for the rifles.
BTW, 6k rounds is not a lot when you have kids that practice rapid fire with quick mag changes. 40 rounds goes in about 15 seconds. Sure beats suppling them with 9MM though.
